A quantitative gait training and/or analysis system includes one or more footwear modules that may include a piezoresistive sensor, an inertial sensor and an independent logic unit. The footwear module functions to permit the extraction of gait kinematics and evaluation thereof in real time, or data may be stored for later reduction and analysis. Embodiments relating to calibration-based estimation of kinematic gait parameters are described.

Wireless and retrofittable in-shoe system for real-time estimation of kinematic and kinetic gait parameters

A rehabilitation machine can have a chassis with actuators positioned behind a patient area. The actuators can have supports projecting toward the patient area and can have respective adapters shaped to engage the legs of a patient at the thigh, the calf, and the foot while the patient is in a standing or walking posture. The actuators can also have motors, transition elements, and linkages connected to apply moments through the adapters to achieve, for each leg, hip adduction/abduction, hip flexion/extension, knee flexion/extension, and foot plantar flexion/dorsiflexion according to signals from a controller. The actuators can be confined to a space, largely behind the patient, such that free arm swing is permitted when the patient is attached.
